RPM is not getting installed for PE3.2

[Deep]

I want to install Puppet Enterprise 3.2 with automated answer file and by creating a rpm. When I am trying to install this rpm by using yum install <rpm name=""> , it gets stuck because this yum command get lock of yum and when installer implicitly calls for yum to install another packages, it is not able to get hold of yum.

To resolve this, I tried to install this rpm with rpm -ivh <rpm name=""> . It got installed successfully once but later on it is giving me following warning and gets stuck.

Warning: RPMDB altered outside of yum.

Any help is appreciated.

Thanks,
